The invention belongs to the technical field of aviation technology structure design, and relates to a wing leading edge hot air anti-icing structure. Comprising a skin (1), a corrugated plate (2), a small beam (3), a first reinforced profile (4), a partition plate (5) and a heat insulation plate (6), the section of the corrugated plate (2) is corrugated, the wave trough position of the corrugated plate (2) is fixed to the skin (1), a gas path in the heading direction is formed between the wave crest and the skin, the small beam (3) is of a plate-shaped supporting structure, the small beam (3) is arranged in the wingspan direction and is perpendicular to the heading direction, and the upper end and the lower end of the small beam (3) are both connected with the skin (1). The small beam (3) divides the leading edge of the wing into a front air chamber and a rear air chamber, the partition plate (5) is arranged along the course, the upper side and the lower side of the partition plate (5) are connected with the skin (1), the rear end of the partition plate (5) is connected with the two first reinforced profiles (4), and heat insulation plates (6) are laid on the corrugated plate (2) in the front air chamber and the small beam (3). The anti-bird-impact capacity is high, and the anti-icing performance is good.

    本发明属于航空技术结构设计技术领域,涉及一种机翼前缘热空气防冰结构。包括:蒙皮(1),波形板(2)、小梁(3)、第一加强型材(4)、隔板(5)、隔热板(6),波形板(2)截面为波形,波形板(2)的波谷位置与蒙皮(1)固定,波峰与蒙皮之间形成沿航向方向的气路,小梁(3)为板状支撑结构,小梁(3)沿着翼展方向布置并且与航向垂直,小梁(3)上下两端均与蒙皮(1)连接,小梁(3)将机翼前缘分成前气室和后气室,隔板(5)沿着航向布置,隔板(5)上下两侧均与蒙皮(1)连接,隔板(5)后端分别与两个第一加强型材(4)连接,前气室内波形板(2)以及小梁(3)上均铺设有隔热板(6)。抗鸟撞能力较强、防冰性能好。
